CROSS REFERENCE TO RELATED APPLICATIONS

[0001] This application is based upon and claims the benefit of priority
from the prior Japanese Patent Application No. 2012-22212, filed on Feb.
3, 2012, the entire contents of which are incorporated herein by
reference.

FIELD

[0002] Embodiments of the present invention relate to a wireless
communication device and a wireless communication method for performing
wireless communication by a plurality of wireless units.

BACKGROUND

[0003] A mobile communication system has been proposed in which when
another device enters a communication area of a certain device, the
certain device automatically performs wireless communication. In such a
communication system, data can be shared among a plurality of devices
without a user's special operation. Further, since the number of devices
sharing the data gradually increases as time passes, the data can be
distributed without providing a server etc.

[0004] The conventional system is convenient and can reduce the user's
burden in that data is automatically transmitted and received regardless
of the intention of the user, but has problems that data is automatically
distributed to unacquainted people and that the user is forced to receive
unnecessary data. That is, in the conventional system, data is
automatically transmitted and received regardless of the intention of the
user, and the received data cannot be easily managed since it is
difficult to check the intention of the user with respect to each of the
transmitted and receive data.

[0006] However, it is not easy to identify that data received by this type
of mobile wireless device used which of wireless systems, and it is
difficult to accurately grasp the intention of the user when receiving
the data.

DETAILED DESCRIPTION

[0023] According to one embodiment, a wireless communication device has a
plurality of wireless units each configured to cover a different wireless
communication range and be capable of receiving data in the corresponding
wireless communication range, a status information generator provided
corresponding to the wireless unit utilized to receive data among the
plurality of wireless units, in order to generate status information
concerning the wireless communication range of the wireless unit utilized
to receive the data, and a storage configured to store the status
information in association with the data.

[0024] Embodiments will now be explained with reference to the
accompanying drawings.

First Embodiment

[0025] FIG. 1 is a block diagram showing a schematic structure of a
wireless communication device 1 according to a first embodiment. The
wireless communication device 1 of FIG. 1 is a mobile wireless device
such as cellular phone, smartphone, game machine, mobile PC, etc.

[0026] The wireless communication device 1 of FIG. 1 has a first wireless
unit 2, a second wireless unit 3, a status information generator 4, and a
storage 5. The second wireless unit 3 covers a broader wireless
communication range than the first wireless unit 2. For example, the
first wireless unit 2 performs wireless communication based on NFC, while
the second wireless unit 3 performs wireless communication using a public
network based on, e.g., a cellular communication system. The first
wireless unit 2 and the second wireless unit 3 can receive the same data.
Further, each of the first wireless unit 2 and the second wireless unit 3
can automatically receive the data transmitted from another wireless
device located in its wireless communication range.

[0027] The status information generator 4 generates first status
information when certain data is received by the first wireless unit 2,
and generates second status information when the same data is received by
the second wireless unit 3.

[0028] The storage 5 stores the data received by the first wireless unit 2
in association with the first status information, and stores the same
data received by the second wireless unit 3 in association with the
second status information.

[0029] The first and second status information is used to judge the
intention of a user when receiving data. That is, the first and second
status information represents information about the wireless
communication range of a wireless unit utilized to receive data. Here,
the term "user" means the owner of the wireless communication device 1 of
FIG. 1, or the owner of a communication partner device which transmits
data to the wireless communication device 1. In the example given below,
the owner of the wireless communication device 1 is referred as a user,
for simple explanation.

[0030] The second wireless unit 2 has a wireless communication range
narrower than the second wireless unit 3. Therefore, there is a high
possibility that the first wireless unit 2 receives data from a
communication partner located close to the wireless communication device
1 of FIG. 1. In this case, there is a relatively strong possibility that
one of the user of the wireless communication device 1 and the
communication partner transmitting the data to the wireless communication
device 1 approaches the other with some intention. Therefore, the first
status information generated when data is received by the first wireless
unit 2 is information indicating that there is a high possibility that
the data has been received with some intention.

[0031] On the other hand, when data is received by the second wireless
unit 3, there is a high possibility that the received data has been
transmitted from an unacquainted communication partner located far away.
Therefore, the second status information generated when data is received
by the second wireless unit 3 shows that there is less possibility that
the data has been received with some intention but a high possibility
that the data is received incidentally.

[0032] As stated above, by generating the first and second status
information, it is possible to estimate the intention of the user when
data is received by the wireless communication device 1 of FIG. 1.

[0033] In order to make it clearer that the user has some intention when
data is received by the wireless communication device 1 of FIG. 1, it is
desirable that the wireless communication range of the first wireless
unit 2 is set narrower. As the wireless communication range becomes
narrower, the distance between the wireless communication device 1 of
FIG. 1 and the communication partner becomes shorter, which shows
extremely strong possibility that the user and the communication partner
approach each other with some intention.

[0034] For example, when the wireless communication range of the first
wireless unit 2 is about several to several tens of centimeters such as
NFC or TransferJet, no data can be transmitted and received until the
wireless communication device 1 of FIG. 1 held by the user and the
wireless device held by the communication partner approach each other,
which makes it possible to suppose that the user and the communication
partner have intention to exchange data.

[0035] On the other hand, it is desirable that the wireless communication
range of the second wireless unit 3 is set sufficiently broader than the
wireless communication range of the first wireless unit 2, so that the
second wireless unit 3 is clearly distinct from the first wireless unit
2. For example, when the wireless communication range of the second
wireless unit 3 is several to several tens of meters or more, data can be
automatically transmitted and received between the user of the wireless
communication device 1 of FIG. 1 and the communication partner even if
one does not approach the other intentionally. Therefore, it is
impossible to consider that there has been any intention that data should
be willingly received. FIG. 2 is a block diagram showing a schematic
structure of a wireless communication device 1a according to a first
modification example of FIG. 1

[0036] The wireless communication device 1a of FIG. 2 has an internal bus
6 connected to the first wireless unit 2, the second wireless unit 3, the
status information generator 4, and the storage 5. The first wireless
unit 2, the second wireless unit 3, the status information generator 4,
and the storage 5 transmit and receive various data and information
through the internal bus 6. This makes it possible to synchronize the
operations of the components in the wireless communication device 1a.

[0037] Each of the wireless communication devices 1 and 1a of FIGS. 1 and
2 has two wireless units (the first wireless unit 2 and the second
wireless unit 3) covering different wireless communication ranges, but
the number of wireless units is not particularly questioned as long as it
is two or more.

[0038] FIG. 3 is a block diagram showing a schematic structure of a
wireless communication device 1b according to a second modification
example of FIG. 1.

[0039] Further, FIG. 4 is a block diagram showing a schematic structure of
a wireless communication device 1c according to a first modification
example of FIG. 3. Similarly to FIG. 2, the components in the wireless
communication device 1b are connected to the internal bus 6.

[0040] Each of the wireless communication devices 1b and 1c of FIGS. 3 and
4 has a third wireless unit 7 in addition to the components of FIGS. 1
and 2. The first wireless unit 2, the second wireless unit 3, and the
third wireless unit 7 cover different wireless communication ranges. For
example, it is assumed that the first wireless unit 2 covers the
narrowest wireless communication range, the second wireless unit 3 covers
the second narrowest wireless communication range, and the third wireless
unit 7 covers the broadest wireless communication range. As a more
concrete example, it is assumed that the wireless communication range of
the first wireless unit 2 is set to several to several tens of
centimeters, the wireless communication range of the second wireless unit
3 is set to several to several tens of meters, and the wireless
communication range of the third wireless unit 7 is set to hundreds of
meters to several kilometers, and status information is separately
generated for the respective wireless units. Since the wireless
communication ranges of the wireless units are greatly different from one
another, if the wireless unit used to receive data can be identified by
the status information, it is possible to correctly grasp that the data
has been received with what kind of intention by referring to the status
information.

[0041] Next, the status information generated by the status information
generator 4 shown in FIGS. 1 to 4 will be explained in detail. As stated
above, the status information is information used to judge the intention
of the user when receiving data. The status information is stored in the
storage 5 in association with the received data.

[0042] Each of FIGS. 5 to 11 is a diagram showing the structure of data
stored in the storage 5. In the example of FIG. 5, status information A
to F are generated by the status information generator 4 corresponding to
six types of received data A to F, and the status information A to F and
the received data A to F are stored in the storage 5 in association with
each other.

[0043] The status information A to F is generated when their corresponding
data A to F are received. In other words, the status information A to F
is generated corresponding to the wireless units receiving the data A to
F. For example, as shown in FIG. 1 or 2, when the first wireless unit 2
and the second wireless unit 3 covering different wireless communication
ranges are provided, the status information A to F differ depending on
which one of the first wireless unit 2 and the second wireless unit 3
receives the data A to F. When status information corresponding to the
data received by the first wireless unit 2 is referred to as the first
status information, and status information corresponding to the data
received by the second wireless unit 3 is referred to as the second
status information, the first status information and the second status
information are different from each other in information showing that the
data has been received by what kind of intention.

[0044] FIG. 6 shows an example in which the status information is more
concrete than FIG. 5. The status information of FIG. 6 includes
information for identifying the type of wireless unit used to receive
data. In the example of FIG. 6, the names of the wireless units are
directly shown, but information for uniquely identifying each wireless
unit (e.g., MAC address, device ID, etc.) may be used instead.

[0045] As shown in FIG. 6, if information for identifying the wireless
unit used to receive data is used as the status information, it is
possible to easily identify which wireless unit receives the data, and to
estimate the intention when receiving the data based on the information
of the identified wireless unit.

[0046] Depending on the situation, there is a case where one type of data
is cooperatively received by a plurality of wireless units, or where the
same data has been received by one wireless unit and will be received by
another wireless unit. In such cases, the status information may include
information of a plurality of wireless units which have received or will
receive the same data. The structure of data stored in the storage 5 in
this case is as shown in FIG. 7, for example. In FIG. 7, the status
information showing "First & Second wireless units" is generated by
synthesizing the status information when the data B is received by the
first wireless unit 2 and the status information when the data B is
received by the second wireless unit 3.

[0047] Instead, as shown in FIG. 8, when the same data has been received
or will be received by a plurality of wireless units (e.g., the first
wireless unit 2 and the second wireless unit 3), the status information
corresponding to a wireless unit (e.g., the first status information)
covering the narrowest wireless communication range in the wireless units
may be used as the final status information.

[0048] When the same data as the received data already stored in the
storage 5 is received by another wireless unit, since their status
information are different, the data and the status information related to
each other can be stored in the storage 5 on each occasion. Instead, the
data and the status information already stored in the storage 5 may be
eliminated so that only the same data newly received and the status
information related to each other are stored in the storage 5. In this
case, the latest status information is constantly stored in the storage
5, which means that the status information is continuously updated.

[0049] For example, it is assumed that data is received by the second
wireless unit 3 covering a broader wireless communication range, and then
the user of the wireless communication device 1 intentionally approaches
the communication partner to receive the same data again by the first
wireless unit 2. In this case, by using newly generated status
information, it is possible to more correctly estimate that the user has
an intention to receive the data.

[0050] When receiving the same data as the data already received,
reception of the data may be stopped at a time point recognized to be the
same data, and a process required after receiving data may be started.
For example, when it is found that the same data has already been stored
in the storage 5 before reception of data is begun, the process required
after receiving data may be started without receiving the data.

[0051] To the contrary, the data and the status information already stored
in the storage 5 may be kept while eliminating the same data newly
received and its status information. That is, the data received first and
its status information may be continuously retained. In this case, since
the status information is not updated, it is possible to prevent the
status information from being rewritten afterwards.

[0052] In FIGS. 6 to 8, information capable of identifying a wireless unit
is used as the status information, but the status information may be a
weighted value which is weighted corresponding to the type of wireless
unit utilized to receive data. FIG. 9 is a diagram showing an example
when using weighted values as the status information. In the example of
FIG. 1, since the wireless communication range of the first wireless unit
2 is narrower than the wireless communication range of the second
wireless unit 3, there is a high possibility that the user or the
communication partner has greater intention to transmit and receive data
when the data is received by the first wireless unit 2 compared to the
case where the data is received by the second wireless unit 3.
Accordingly, the weighted value as the status information corresponding
to the data received by the first wireless unit 2 is set larger than the
weighted value as the status information corresponding to the data
received by the second wireless unit 3. In the example of FIG. 9, the
weighted value as the status information corresponding to the data
received by the first wireless unit 2 is set to 10, while the weighted
value as the status information corresponding to the data received by the
second wireless unit 3 is set to 2.

[0053] According to FIG. 9, the intention of the user when receiving data
can be estimated by the level of the weighted value for the status
information. For example, when a larger weighted value is set for a
wireless unit covering a narrower wireless communication range, it is
possible to intuitively know that the larger weighted value shows that
the data is received with strong intention. To the contrary, a smaller
weighted value may be set for a wireless unit covering a narrower
wireless communication range. Also in this case, it is possible to
intuitively know that the smaller weighted value shows that the data is
received with strong intention.

[0054] FIG. 10 is a diagram showing an example where a plurality of
weighted values are synthesized to set the final weighted value. As
explained in FIG. 7, when the same data has been received or will be
received by a plurality of wireless units, the status information may be
synthesized. When weighted values are used as the status information, the
final weighted value may be obtained by simply summing up the weighted
values corresponding to a plurality of wireless units which have received
or will receive the same data. For example, in FIG. 10, the weighted
value corresponding to data F is 12 (=10+2) since the first wireless unit
2 having a weighted value of 10 and the second wireless unit 3 having a
weighted value of 2 have received or will receive the same data.

[0055] In the example of FIG. 10, when the second wireless unit 3 tries to
receive the data F totally six times, the final weighted value also
becomes 12. It is not necessarily easy to determine that the user has a
stronger intention to receive the data F in either of when the first
wireless unit 2 and the second wireless unit 3 try to receive the data F
once respectively, or when only the second wireless unit 3 tries to
receive the data F six times.

[0056] Accordingly, as shown in FIG. 11, when a plurality of wireless
units having different weighted values try to receive the same data, it
is also possible to select a wireless unit corresponding to the largest
weighted value from the wireless units trying to receive the same data,
in order to use the weighted value of the selected wireless unit as the
final weighted value, instead of summing up the weighted values. For
example, when the first wireless unit 2 and the second wireless unit 3
try to receive the data F of FIG. 11, a weighted value of 10
corresponding to the first wireless unit 2 becomes the final weighted
value.

[0057] As stated above, in the first embodiment, when data is received by
any one of a plurality of wireless units covering different wireless
communication ranges, the status information for judging the intention
when receiving the data is stored in the storage 5 in association with
the received data. The status information makes it possible to grasp that
the data has been received with what kind of intention, and to recognize
the importance of the received data.

Second Embodiment

[0058] A second embodiment is characterized in that the data stored in the
storage 5 is displayed based on the status information.

[0059] FIG. 12 is a block diagram showing a schematic structure of a
wireless communication device 1d according to the second embodiment.

[0060] The wireless communication device 1d of FIG. 12 may be a mobile
wireless device such as a cellular phone, or may be a stationary wireless
device such as a base station and a digital signage.

[0061] In addition to the components in the wireless communication device
1 of FIG. 1, the wireless communication device 1d of FIG. 12 has a
display 8 and a display controller 9. The display controller 9 grasps the
intention of the user when receiving data, based on the corresponding
status information stored in the storage 5, and selects at least partial
data from the storage 5 in accordance with this intention to display it
on the display 8.

[0062] For example, when data received with the user's strong intention is
found from the status information, the display controller 9 displays the
data by priority. Accordingly, the data which is regarded as important by
the user is displayed by priority, which improves convenience for the
user.

[0063] Note that the user should not be limited to the owner of the
wireless communication device 1d, and may be the administrator or
installer of the wireless communication device 1d. Further, when the
wireless communication device 1d is a digital signage, the user may be an
agency relating to its installment.

[0064] As stated above, in the second embodiment, since data stored in the
storage 5 is selected based on the status information stored in the
storage 5, and displayed on the display 8, the data can be displayed in a
manner considering the intention of the user when receiving the data.
Accordingly, the user can easily find the data attractive to the user on
the display 8, which improves convenience for the user.

Third Embodiment

[0065] A third embodiment is characterized in that the data stored in the
storage 5 is transmitted based on the status information.

[0066] FIG. 13 is a block diagram showing a schematic structure of a
wireless communication device 1e according to the third embodiment.

[0067] The wireless communication device 1e of FIG. 13 also may be a
mobile wireless device such as a cellular phone, or may be a digital
signage installed in the city streets etc.

[0068] The wireless communication device 1e of FIG. 13 has a wireless
transmitter 10 instead of the display 8 and the display controller 9 in
FIG. 12. When it is identified by the status information to be data that
the user received with the strong intention, the wireless transmitter 10
transmits the data by priority. Therefore, the data attractive to the
user is transmitted by priority, and the receiver of the transmitted data
can receive data of high importance by priority, which improves
convenience.

[0069] Since the data attractive to the user of the wireless communication
device 1e of FIG. 13 can be transmitted to a specific person approaching
the user, the same data can be easily shared among people having the same
liking, with simple steps.

[0070] In FIG. 13, the wireless transmitter 10 is arranged separately from
the first wireless unit 2 and the second wireless unit 3, but data may be
transmitted using the first wireless unit 2 or the second wireless unit
3. The block configuration in this case is as shown in FIG. 14, in which
a wireless communication device 1f does not have the wireless transmitter
10.

Another Embodiment

[0071] In the examples explained in the first to third embodiments, the
received data and the status information are stored in the storage 5 in
association with each other, but distribution requirement information of
the data may be additionally stored.

[0072] FIG. 15 is a diagram showing the structure of data stored in the
storage 5 when additionally storing the distribution requirement
information. There is no need to add the distribution requirement
information for all types of data. Accordingly, in the example of FIG.
15, distribution requirement information for data C and E are omitted.

[0073] The distribution requirement information can specify the conditions
when transmitting the received data stored in the storage 5. This
eliminates a fear of transmitting data to an unexpected communication
partner.

[0074] Here, the distribution requirement information may be determined
for each wireless unit. For example, only the first wireless unit 2
covering a narrower wireless communication range may be allowed to
transmit (distribute) data. Since the first wireless unit 2 can transmit
data only when its communication partner is located close, there is less
possibility that the data is transmitted to an unexpected communication
partner through the first wireless unit 2.

[0075] Further, the distribution requirement information may specify
performing an authentication process before transmitting data. The block
configuration in this case is as shown in a wireless communication device
1g of FIG. 16.

[0076] The wireless communication device 1g of FIG. 16 has an
authentication unit 11. When the distribution requirement information
specifies performing the authentication process, the authentication unit
11 performs the authentication process with a communication partner, and
only when the authentication has been successfully completed,
corresponding data is transmitted using, e.g., the first wireless unit 2.

[0077] Each of the wireless communication devices 1 to 1g according to the
above embodiments may be any one of a mobile wireless device such as
cellular phone, smartphone, game machine, laptop PC, etc.; a stationary
